Companion app for the JMP eSIM Adapter
About this app
JMP SIM Manager is a fully free and open-source companion app for the JMP eSIM Adapter. The JMP eSIM Adapter is a removable eSIM chip that enables any device, not just those with included eSIM chips, to make use of downloadable eSIMs.
JMP SIM Manager provides management features such as adding, deleting, enabling, and disabling eSIM profiles for the adapter, and is the easiest option to manage your eSIM Adapter on compatible Android host devices. The manager app is not required once a profile has been downloaded and enabled on the adapter. In other words, you can use a compatible Android device to download your eSIM profile of choice onto the adapter, and then insert the adapter into any device -- Wi-Fi hotspots, dumb phones, laptops -- and the adapter will simply appear as a regular SIM card to those devices.
This app also includes a quick compatibility check to determine whether your Android device can be used to manage a JMP eSIM Adapter. Although the eSIM Adapter will work with almost any device once an eSIM profile is loaded, management requires some specific features that may not be present on a small percentage of Android devices. However, even if your Android device is deemed incompatible, you can still manage the adapter from another Android device, using a PC/SC reader on a PC, or, as a final fallback, through the SIM Toolkit menu along with a self-hostable remote server to handle TLS termination.

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be chat.jmp.simmanager is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, jmp-v1.5.1 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall JMP SIM Manager first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of JMP SIM Manager, and a listing is removed when the evidence for it stops holding up.
